Please explain that why the volume of the ice is neglected ur at a fonstant temperature and pressure. find ah and au if the latent heat of nslon of

6. 1 mole of ice at 0°C and 4-6 mmHg pressure is converted to water vapour at a fonstant temperature and pressure. Find AH and AU if the latent heat of nslon of Ter 1s 80 cal/and latent heat of vaporisation of liquid water at 0°C 8 696 cal/g and the volume of ice in comparison to that of water (vapour) 1s 1eglected.
